Re: A tale of woe, including carelessness, stupidity and laziness....

Dec quad high boards had metal extractor handles which were possibly attached to metal rails, and if the wiring was wrong, could deliver a shock. Microdata card extractors were always engaged to a rail that was metal, and in one site I was at, there was a CE sized hole in the wall behind a sys

Re: A tale of woe, including carelessness, stupidity and laziness....

As a child I remember getting a shock from a fridge and being "thrown" across the room into the wall opposite. I really did crash into the wall quite hard, so I can imagine it being very easy for the shock to cause other injuries. Regards Rob On 26/08/2015, tony duell wrote: >> Remember that mo

RT-11 on a PDP-11/10

Hi all. Update have an 11/10, that was recently powered on again for the first time in I don't know when. After some fiddling with the RX01 disks, we put an RL11 and an RL02 on it. Lots of space, I know. :-) Also, we have RT-11 running on it. And for fun, we wanted to run the original Tetris. Bu

Many Manuals - Also Boxes of Fan Fold Paper

Since the topic of hard copy manuals is at least on a few minds, I thought I would mention that I have at least 20 feet of mostly DEC PDP-11 related manuals which will have to be tossed if a home can't be found. While I estimate that at least 90% of the DEC manuals are on bitsavers, some individ

I'll admit to being surprised at the cheapness of the keyboard. Here I expected to find a true mechanical type, like the early IBM machines - what I found is a step-down from the C-64. The switching side is what I'd term a 'membrane sandwich. There are three layers in the stack, with upper & lower

I just noticed the September 2015 issue of Nuts & Volts has, right on its cover, a project to outfit a Commodore PET with color (digital RGBI) output.
